Answer 2

$\underline{\underline{\huge\bold{Answers}}}$ :-

(a) The tiny holes formed in the teeth are known as ‘cavities’ or ‘dental caries’ .

(b) When a person eats sugar-containing food, then the bacteria present in mouth act on sugar present in food to produce acids. these acids first dissolve the calcium salts from tooth enamel and then from dentine forming tiny holes (or cavities) in the tooth over a period of time.

(c) Mohan's dental cavities or holes were first cleaned by the dentists and then 'filled' with appropriate filling material.

(d) The sticky, yellowish layer on the teeth is known as ‘dental plaque’.

(e) If the teeth are not cleaned regularly, then they become covered with a sticky, yellowish layer of food particles and bacteria cells called ‘dental plaque’

(f) I will give following advice to Mohan to avoid such dental problems in future :-

1. Mohan should eat less of surgery food such as toffees, chocolates and sweets, etc. He should also avoid drinking too much of sweetened drinks such as Coca-Cola, Pepsi, etc.
2. Mohan should brush his teeth regularly with a toothpaste after eating food. This will remove dental plaque before bacteria produce acids.
3. Mohan should get his teeth examined by a dentist at least once in three months.
